I can speak to that.
Smallpox is not vaccinated for at all. Smallpox, as you may know, has been eliminated from the globe.
There are certainly some stores of smallpox in some labs; I believe the U.S. has it. There's a potential for smallpox to be used as a bioweapon. What we're using and keeping in our stockpile is vaccines against smallpox. Hopefully, smallpox will not emerge in the world at all and we'll never have to vaccinate against smallpox again.
